iOS camera not working

Hello, this is my first Topic here…
i have tried Jisti in iOS Mac/Iphone and the camera does not work, what i found out is that the Video constraints are not getting contructed therefore when you try the Camera to start with the icon Mute/Unmute Camera the Camera does not work

this is what i get in an Android Device when i Unmute the Camera using the Icon

this is what i get in an Iphone Device when i Umute the Camera using the Icon

Perhaps someone can check if there is an issue in contructing the Video object using iOS

Thank you in advanced

Best regards,
